commit r16-6100-g3f7bdc190f3ef483283e51b5f4ef02401a1ed913 Author: Alexandre Oliva <[email protected]> Date: Sat Dec 13 04:12:02 2025 -0300 [testsuite] xfail vect-121.c on ia32 [PR119293] Once fre5 resolves conditional of the guard block for the vectorized loop, cfgcleanup removes the edge that bypasses it, adjusting the other edge probability, but not the edge's dest's count. The blocks get combined, and their counts are merged, but nothing adjusts the counts of the block that lost an incoming edge. The incoming counts remain inconsistent from that point on, and get reported as "Invalid sum of incoming counts" in the tree dump where vect-121.c checks for the absence of this error. That was added in response to a fix for a vectorizer profile count management problem. This is a different profile count management problem, so it makes sense to silence this failure marking it as expected. for gcc/testsuite/ChangeLog PR tree-optimization/119293 * gcc.dg/vect/vect-121.c: XFAIL on ia32.
